GUARD.

Application filed September 10, 1913. Serial No. 789,156.

To all whom it may concern:

Be it knownthat I, GEORGE W. WOOD, a citizen of the United States of America, and a resident of Syracuse, New York, have invented certain new and useful Improvemen-ts in Guards, ofwhich the following is a specification.

My invention relates to improvements in guards and primarily tothat type of guard to be used in inclosing a man-hole.v It may also be usedas a guard for young children,

and by a slight modification, such as the ad: dition ofcasters, it may serve as a babywalker.

The object of my invention is. to construct a guard of suitable configuration for its several purposes that may befolded 1n the most compact manner for transportation) and which, when opened and ready for use, will present a rigid barrier. 1-

p Myinvention comprises upper and lower members. of suitable configuration to define the guarded space with pivoted supports.

to hold them in spaced relation when the guard is open, several of the supports at one end thereof being provided with locking means to maintain the guard in an open position when in use. 3

My invention also embodies other features which will be more fully described and re ferred to in the accompanying. specification.

Referring. to the accompanying. drawings, in which corresponding parts are designated by corresponding marks of reference, Fig

ure 1 1s a. perspective view, showing my invention in a closed position, ready for trans-.

portation. Fig. 2 is a perspective view of my invention, showing :the first movement taken toward opening my device. Fig. 3 is aperspective view of my invention, showing my device fully opened, and the front supports ready to assume their locked position. Fig. 1 is aperspective view of my invention, fully opened and ready for use, the.

front supports being locked. Fig. 5 1s. a detail perspective view of the pivotal mount-' ing .of the halves of the lower member. Fig. 6 is a detail perspective view means.

The device as shown comprises an. upper member 1 and a lower member 2, the upper member being made of suitable material preferably iron, in channel form, the lower" member being formed of angle iron, and divided into two halves 2?- and 2". As is shown serving to hold when in of the locking '26 on the outer ends of 1 1, respectively.

in the drawings, I haveindicated the upper and lower members 1 and 2, respectively, as being annular, but I do not wish to limit myselfto that particular shape as the members may be oval, square, rectangular or polygonal in configuration as is preferred. My device, when used as a manhole guard, has by preference a portion of the upper member 1 cut away to permit access to the manhole.

' On the under side of the upper member 1 are brackets 3, 1, ,5, 6 and 7 formed with flared ears and having suitablepivot pins mounted therein, to which are pivotally secured the ears 31 formed on the nipples 32 which nipples are on the upper ends of the supports 8, 9, 10, 11 and 12, these supports, an open position, the upper and lower members in spaced relation. Open position is referred to as that position the guard assumes when in position over a man-hole and closed position to that position in which the guard is partly or wholly closed and ready for transportation.

Owing to the peculiarity of my construction it is essential that be located around the upper member 1, and that the pivots thereof be parallel with each other, the pivot of the support 8 being out ofthe linejoining the pivots 9 and 10. The-supports 8, 9, and 10 are also pivoted to the lower member 2, in substantially the same manner as they are attached to the upper member. The lower member 2 of my device is of the same configuration as the upper member, the two halves thereof being pivotally jointed together by brackets 13 and 14, attached to each half of the lower member by suitablebolts, indicated at 15;

Mounted on the lower ends of the supports 9 and 10 are nipples terminating in T- heads 16 and 17 through the opposite ends of which transverse pivots 18 and 19, and, 20 and 21 mounted in the outer ends of the brackets 13 and let, respectively, pass. F or the purpose of limiting the downward movement of the halves of the lower member 2 in respect to'each other when in an open position, lugs 22 and 23 are formed on the sides of the flared T-heads 16 and 17 above the bottom thereof, which lugs are adapted to engage with projections 25 and the brackets 13 and Mounted on the forward side of the upper the supports 8, 9 and face of the lower member 2 are studs and 28 which are adapted to be engaged sliding collars 29 and 30 slidably mounted' by a bayonet joint ora slot and pin connection on the lower ends of the supports 11.

and 12, which serve, when positioned and rotated over the projections 27 and 28, to hold the guard in a rigid and locked posi tion.

For the purpose of clearness, the opera-1 ing downward movement to the uppermost reanportion of the upper member 1 and causing thatzmember to assume a horizontal position. The guard .has now a. position substantially that as shown in. Fig. 3, and the last movement necessary to lock the guard in openposition is that the supports l1 and 12 be swung outwardly and down wardly on their tangential pivots, and that the sliding collars 2,9 and 30 on the lower:

ends of" the said supports be shifted downwardly on the pins and over the projections 27 and 28 whereupon the collars on the for ward half 2 of the lower memberu2iare turned upon their aXes and locked by the annular slots in the collars. When it is de-' sired to-closethe guard,. the collars 29 and 30 are rotated upon their axes and then.

j movedupwardly on the supports 11 and '12,f 'jwhereby they are disengaged fromcthe pro-- the; lower member. The supports-1L and12 v are then swung inwardly and the front half jeotions 2-7 and 28 on the ,front half- 2 of.

2. of the lowermember 2 is then raised to a vertical position and the; rear half32? on:

the lower member is moved to acorrespondmg positlon, which movement causes the upper member 1 to assume a. vertical posi.-

.tionbetweenthe front half 2. and the. rear half ,2? of the lower member 2, isjshown to secure by Letters Patent 1. In a device of the. character described,:

the combination of an upper and lower member, more than two supports pivotally' mounted on the upper and lower. member and at difierent points thereon, the said supports having parallel pivots, and supports connecting the upper and. lower mem- (fopiesof thispatent may be obtained for five cents each; by addressing. the dommissioner 7 Washington, 20.0.?

Having thus described my invention; what I desire 'oted together, supports pivotally mounted on the upper member and to one part of the "lower member, and both parts of the lower members; and: detachably secured to the other part of the lower member respectively.

3. In a deviceot the character described the combination. of an. upper member and a lower; member having suitable? brackets mounted thereon, a plurality of supports mountedlinzbracketson the upper and lower 'members,a support pivoted in a bracket on the upper member, and means-mounted on the lower end ot the last namedsupport for detachably engaging the lower member and locking the. members .inaopen position.
